Could you tell me the type of connector I need for the two signal inputs on the front of the device.

Also there is another socket on the back of the device near the USB input, what is that for?

Many thanks,

The front connectors are called BNC
You can use the PROBE60S for these.

The back RCA connector is the function generator.
